Upcoming GB active substance renewal submission deadlines

Apply for active substance renewal by the relevant deadlines to keep products on the GB market.

Under the GB Biocidal Products Regulation (GB BPR), active substance approvals will expire unless a renewal application is submitted at least 550 days before their expiry date.

The 550-day deadlines are coming up for the following active substance/product type combinations under GB BPR:

28 October 2026

  • calcium dihydroxide / calcium hydroxide / caustic lime / hydrated lime / slaked lime (CAS 1305-62-0 EC 215-137-3) in product types 2 and 3
  • calcium magnesium oxide / dolomitic lime (CAS 37247-91-9 EC 253-425-0) in product types 2 and 3
  • calcium magnesium tetrahydroxide / calcium magnesium hydroxide / hydrated dolomitic lime (CAS 39445-23-3 EC 254-454-1) in product types 2 and 3
  • calcium oxide / lime / burnt lime / quicklime (CAS 1305-78-8 EC 215-138-9) in product types 2 and 3
  • chlorocresol (CAS 59-50-7 EC 200-431-6) in product types 1, 2, 3, 6, 9, and 13


Any person, company or task force/consortium can support an active substance/product type combination for renewal – it doesn’t have to be the original supporter.

Check the GB Article 95 List to see who the original supporters were.

If any of these active substance/product type combinations are important to you, consider contacting your supplier to let them know.

If a renewal application is not submitted for the above active substance/product type combinations under GB BPR, the approvals will expire. This means the active substances will no longer be able to be used in biocidal products of the relevant product types in GB.

In addition, articles treated with such products will no longer be able to be placed on the market in GB.

Upcoming GB active substance expiry dates

Biocidal products must be phased off the GB market.

The active substance/product type combinations listed are due to expire under the GB BPR on the following dates:

31 January 2027

  • hydrogen peroxide (CAS 7722-84-1 EC 231-765-0) in product type 6

Once the approvals expire, the active substances will no longer be able to be used in biocidal products of the relevant product types in GB.

In addition articles treated with such products will no longer be able to be placed on the market in GB.

If you hold an affected GB BPR product authorisation or Control of Pesticides Regulations (COPR) product approval, we will contact you about cancelling or revoking your authorisation or approval. You will have an opportunity to submit comments or additional information and we will take account of these when finalising our decision.
